scope:

Purpose. This instruction establishes a Chairman of the Joint Chiefs of Staff (CJCS) requirements management structure (RMS) for the Global Combat Support System (GCSS) family of systems (FOS). The GCSS FOS RMS consists of a General/Flag Officer Steering Group (GOSG), a planners board (PB), and situational-dependent working groups (WGs) to review functional requirements for systems integration, to foster interoperability and information assurance across the GCSS FOS, to synchronize fielding of schedules, and to propose and, if applicable, approve the policies and procedures that help the Department of Defense (DOD) meet joint combat service support (CSS) requirements. This RMS addresses issues that cut across the GCSS FOS and will facilitate the delivery of the required functionality in a timely manner. It brings together the requirements generation (reference a), acquisition, planning, programming, and budgeting system (PPBS) communities in a partnership to identify and resolve GCSS FOS issues that cut across communities. It assigns supporting responsibilities for the Office of the Secretary of Defense (OSD), Joint Staff, Services, Defense agencies, combatant commands, and other activities. DOD acquisition oversight of the GCSS FOS will be under the DOD 5000 series overarching integrated product team assigned for each GCSS system.

Applicability. This instruction applies to OSD, the Joint Staff, combatant commands, Services, and Defense agencies and other activities.
